Non lift cord operated blind structure

ABSTRACT

A non lift cord operated blind structure comprises a cordless blind having a set of vertical-type lateral elements symmetrically arranged to lead through passages disposed at both left and right sides of a blind body, a pair of flexibly-bound clip elements attached at both lateral bottom edges of the blind body thereon to be respectively clamped to the lateral elements thereby, and decorative covers symmetrically fixed at both ends of a headrail. Therefore, the clip elements can be directly adjusted upwards or downwards at the lateral elements thereon before clamped tight thereto to control the collection or expansion of the blind body thereby without the use of any lift cords to avoid the danger of strangling children by dangling lift cords. Besides, the decorative covers are applied to conceal the lateral elements therein, enhancing the aesthetic appeal of the cordless blind as well as achieving safer operation thereof.

BACKGROUND OF THE INVENTION

The present invention is related to a non lift cord operated blindstructure, comprising a cordless blind made up of a blind body, and apair of flexibly-bound clip elements stably clamped at a set of lateralelements symmetrically arranged at both left and right sides of theblind body thereon wherein the clip elements can be directly adjustedupwards or downwards to control the collection or expansion of the blindbody thereby without the use of any lift cords to avoid the danger ofstrangling children by dangling lift cords. Besides, decorative coversare provided to conceal the lateral elements therein, enhancing theaesthetic appeal of the cordless blind as well as achieving saferoperation thereof.

A conventional blind structure usually found on the market is made up ofa roller gear set reciprocally operated with a lift cord set and astring ladder set, which are tediously assembled in a rathertime-consuming and painful manner. Besides, when the blind body thereofis raised in a collected state, the lift cord will suspend downwards andexposed outside for a certain length. As a result, children playingaround can easily get caught in the dangling lift cord that, if thechildren are not released immediately there-from or when the lift cordis unfixed to raise upwards, can accidentally strangle and hurt thechildren caught therein. Thus, the conventional blinds are quite unsafein application thereof.

SUMMARY OF THE PRESENT INVENTION

It is, therefore, the primary purpose of the present invention toprovide a non lift operated cord blind structure, comprising a cordlessblind made up of a blind body, and a pair of flexibly-bound clipelements stably clamped at a set of lateral elements symmetricallyarranged at both left and right sides of the blind body thereon whereinthe clip elements can be directly adjusted upwards or downwards at thelateral elements thereon to control the collection or expansion of theblind body thereby without the use of any lift cords to avoid the dangerof strangling children by dangling lift cords, achieving saferapplication of the present invention.

It is, therefore, the second purpose of the present invention to providea non lift cord operated blind structure wherein decorative covers areprovided to conceal the lateral elements therein and provide anornamental effect thereby, enhancing the aesthetic appeal of the presentinvention thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1 showing an exploded perspective view of thepresent invention (accompanied by FIG. 2 showing an assembledperspective view of the present invention). The present inventioncomprises a cordless blind 10 made up of a blind body 12, and a set ofvertical-type lateral elements 11 (like strings or cords 111 as shown inFIGS. 1, 2) symmetrically disposed at both left and right sides thereonto be sequentially guided through passages of a plurality of elongatedpieces 13 arranged in equal space at the blind body 12 thereon. At thelower ends of the lateral elements 11 are symmetrically attached a pairof clip elements 16 each having a clamping portion 161 with serratedteeth defining thereon and equipped with a flexible clamping ability viaa torsional spring pivotally bound therein. The clip element 16 also hasa press portion 162 symmetrically disposed at the other side thereof anda protrusive flange 163 with a thru-hole 1631 disposed thereon to befixed at an appropriate position of the blind body 12 thereby. The upperends of the lateral elements 11 are securely attached to an appropriateposition at the underside of a headreail 15 having a pair of L-shapedlateral decorative covers 17 symmetrically fixed at both ends thereon toconceal the lateral elements 11 thereby.

Please refer to FIG. 3. In application, the headrail 15 of the cordlessblind 10 is fixed to a connecting surface 20 disposed on top, and thebottom ends of the lateral elements 11 are fixedly attached to anotherconnecting surface 20 disposed at the bottom thereof so as to stretchupright the lateral elements 11 in the full length thereby. To collectthe blind body 12 in a folded-up state, force is applied to the pressportion 162 of the clip element 16 clamped at the bottom edge of theblind body 12 thereof to open up the clamping portion 161 and form amovement space 164 thereby so that the clip element 16 can be freelymoved upwards as shown in FIG. 4 to bring upwards the blind body 12therewith and sequentially fold it up in overlapped layers thereby. Whenthe blind body 12 is collected and raised to a desired position, thepress portion 162 of the clip element 16 is released from the forceapplied, permitting the clamping portion 161 to flexibly rebound via thetorsional spring mounted therein and mesh up again so as to clamp tightagainst the lateral element 11 for the relocation of the raised blindbody 12 collected above and limited in position by the clip element 16thereof as shown in FIGS. 5, 6. To suspend downwards the blind body 12in an expanded state thereof, force is applied again to the pressportion 162 of the clip element 16 to open up the clamping portion 161with the movement space 164 revealed thereby so that the clip element 16can be moved downwards to lower the blind body 12 suspending naturallydownwards in a fully-expanded state. Therefore, the cordless blind 10 ofthe present invention is easily and speedily operated to raise or lowerthe blind body 12 without the use of any lift cords to avoid the dangerof strangling or hurting children due to the dangling lift cords of theconventional blind structure. Besides, the decorative covers 17 areapplied to enhance aesthetic appeal of the cordless blind 10 as well asachieve safer operation thereof.

Please refer to FIG. 7. Depending on the height drawn between the topand bottom connecting surfaces 20, the decorative cover 17 can be madeinto multiple sections and layers that are mutually combined and fixedinto one unit.

Please refer to FIG. 8 showing another embodiment of the presentinvention. The lateral element 11 of the cordless blind 10 can also bemade in a rod body 112 guided through a flexible clip element 16′equipped with a symmetrically-extending and resiliently-bound arcuateretaining portion 161′ and stably held in place by an accommodatingspace 1631′ defined by the arcuate retaining portion 161′ thereof. Atthe upper edge of the flexible clip element 16′ thereof is appropriatelydisposed a protrusive flange 163′ having a thru-hole 1631′ definingthereon to be reciprocally attached to the blind body 12 thereby.

Furthermore, the cordless blind 10 thereof can be made into varioustypes of blinds such as the Roman blinds as shown in FIG. 1, and thehobbled Roman shades as shown in FIG. 7, etc.
